Very rare large copper plates carved for the famous portfolio Ten Etched Plates of Chicago edited in 1931 and limited to 200 copies.
One copper plate appears to be an unrealized print the others correspond to the prints called Michigan Avenue 1 & 2, the Cathedral and the most impressive print The Wacker Drive which shows a skyscraper at night as a lighthouse.
This engraving work playing with different levels of black is particularly difficult and requires great finesse of execution.
Engraved brass of this size is usually erased for repeated use.
THIS TYPE SET IS VERY RARE.
Five copper plates, 280 x 375 ; 320 x 260 ; 300 x 204 ; 230 x 360 and 355 x 260 mm. Engraved signature.
